637343-84-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 637343-84-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,7,3,4 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 637343-84:
(8*6)+(7*3)+(6*7)+(5*3)+(4*4)+(3*3)+(2*8)+(1*4)=171
171 % 10 = 1
So 637343-84-1 is a valid CAS Registry Number.
